Hello again everyone! I've got myself a problem trying to run a java application (with calls to Windows native libraries) on Wine 1.2. That aside, the problem is explained with this little example: Code: $ wine java -version java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02) Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode) $ wine java -xmx1024

The memory consumed by the code compiled is huge in server applications. And it is not shared by different virtual machine instances. By contrast, shared libraries are memory mapped, therefore they are shared between different instances of the executables using them. It is posible to throw away code after using it, but then compilation cost would be repeated. And dynamic compilation prevents

It doesn't output class constructors yet, so the output won't actually work. I think Peter has a patch fixing that, so you might want

In our environment we have many legacy application servers running apache/jserv. There is a web server front end, then a couple of load-balanced java servers on the backside. One of the problems we are faced with is hung or stuck jvms. I have looked at the java process with the ps command, and there are many times when URL(s) do not respond, yet the java looks healthy, at least from the OS

The interface files you see are for a prototype of Java Tsan that's internal to Google. It's for use by a JDK that we customized with extensive JVM patches, and enables running the Tsan engine on Java and native code simultaneously. We presented this prototype recently at the JVM Language Summit. Here's the talk: https://www.youtube.com/watch?v=UykhZ36W04I We are starting to explore

Hello, I am Ramon Garcia Fernandez. My interest in LLVM is to develop an interface for Java virtual machine bytecodes, so that Java programs can be run under LLVM. You may ask why not using the Java virtual machine. Although it may be improved, there are some misfeatures in it. This is what I have learned. It makes the communication with native code too expensive. Passing an array from native to

Hi Minas, Thanks! I wasn't aware that VMKit had the ability to generate llvm code from .class / .jar files - I thought all of its code-generation capabilities were very closely tied to the VM itself. I'll look into this. The motivation behind this project is to be able to get both the small size and fast startup times of Avian, along with the speed of llvm-generated code. Currently,

Hi, I'm trying to use the Java front-end (which, based on svn commits, appears to be three-years-dead), and I'm running into some build errors. In that time did llvm change from building with exception handling and rtti to building without? I remember reading somewhere that llvm code should use dyn_cast instead of dynamic_cast. Do these need to be changed here? A little background:

You probably want to sit down and have a long talk with Jeroen Frijters, the principal behind the IKVM project.

Oups, sorry for the mistake, llcj (not llc:)) is not more maintained!

Hi, I wanted to use VMKit project to convert Java Bytecode to LLVM IR bitcode. But I do not know how to start, since I came to know that VMkit is written for llvm -3.3 version, but I want it for latest LLVM version 6.0.1. So, could you please suggest me, whether I have to write it whole project from scratch to meet my requirement of latest llvm version, or can use existing project by building

Hi Nicolas, I found a 32bit Lucid machine (but it'd be great if there was a working 64bit version though). Everything was checked out this morning. I now am able to build vmkit with this configuration: ./configure --with-llvmsrc=/home/zoewolk/RESEARCH/llvm --with-llvmobj=/home/zoewolk/RESEARCH/llvm --with-gnu-classpath-glibj=/home/zoewolk/RESEARCH/classpath-0.97.2/lib

Hi, I'm new to VMKit and I'm trying to use its AOT Java compiler but I'm immediately getting an error message which I don't understand. Everything was compiler as suggested in the Getting Started tutorial, using GNU Classpath. I try to run: llcj ../../tools/trainer/Release+Asserts/HelloWorld.class and get the following output: Can not materiale a function in AOT mode.0

I did not choose Java when I installed CentOS 4.4 and I want to install a JDK to do Java programming. What is the default Java JDK for CentOS 4.4 ? I see under YumEx very little which looks like a Java JDK. Is there one in the distribution ? Is there a way to get Sun's latest JDK 5 installed safely and successfully on CentOS 4.4, perhaps via an RPM for it tailored to CentOS 4.4, or should

I lost my harddrive, and have had to reinstall. This time, I am being a bit smarter on imaging, but still got to get things installed... Installing Freemind. It needs Java JRE. So after lots of pain, and reading past messages, I got jre-1_5_0_09-linux-i586.rpm from sun and installed it. Then I tried to follow Jim Perrin's recommendation to install from jpackage.org the

Does there exist *anywhere* a Java web browser plugin for 64-bit FireFox? The SUN 1.6<mumble> JDK (jdk-6u18-linux-amd64.rpm) does NOT include the Java web browser plugin library. java-1.6.0-openjdk-1.6.0.0-1.2.b09.el5.x86_64.rpm does not have one either. Should I install the *32-bit* SUN 1.6<mumble> JDK and use the 32-64 bit wrapper? I've searched the web and read the wiki

Hi there, I am trying to diagnose a performance problem on a Sun T5120 running Solaris 10. I see general poor performance using Java and, in particular, loading classes. I have developed a simple java test that loads all of the classes in a Crystal Reports JAR file (around 7000 classes) which takes much longer on the T5120 (40 secs) than on a Core 2 Duo windows PC (5 secs). I recognise that this
